Wall Frame. (Supporting Conventional Roof Framing)
Determine the most economical size, span & spacing of the following members
1. Bottom Wall plate – not trenched.2. Top Wall plate – not trenched (to support rafters @ 600mm c/c)3. Common Studs at 600mm c/c (not notched for erection bracing)4. Noggings5. Jamb Studs (studs at sides of openings)6. Lintels7. Eaves Beams (Verandah Beams)8. Tie down spacing 1.800
Use Preliminary Calculations from Roofing exercise 2.
